I've only used one, and while there's some distortion compared to a regular mirror, it's not so noticeable that it bothers me. You can stick it anywhere, so I'm using it where my baby can see it, and I feel safe because it won't break. VECLO's rounded corner, shatter-resistant acrylic mirror, can be freely combined and used for various purposes. - Brand: VECLO - Design: Rounded corners - Material: Acrylic - Features: Shatter-resistant - Uses: Multi-purpose - Size: Customizable Thank you for viewing.
